1 / 1Pages

Miniature HV Power Supplies TF Series FEATURES • Ultra-compact, PCB mountable • Low ripple, 30mVp-p • Low Noise due to metal shielding • Well-regulated, high performance • External potentiometer or external control voltage programming • Arc and continuous short circuit protection SUMMARY TF Series are miniaturized, well regulated high voltage power supplies suitable for photomultiplier. They feature exceptionally low noise, external potentiometer or voltage control and fully protection against arc and continuous output short circuit. Output voltage (kVdc) 0 to 1.25 0 to 1.25 Model Positive polar output TF-1.25P-12 TF-1.25P-15 Negative polar output TF-1.25N-12 TF-1.25N-15 Output voltage range for this output current is 50% to 100% of maximum output voltage. Output current must be derated linearly when operating at levels below 50% of the output voltage capability. Input voltage/current (TF-1.25P-12,TF-1.25N-12) +12Vdc ±1Vdc, 95mA Typ (TF-1.25P-15,TF-1.25N-15) +15Vdc ±1Vdc, 90mA Typ Output control By external 50k potentiometer or external control voltage(Vcon-in) 0 to 5Vdc(Input impedance 80k) Regulation Line : ±0.01% of max voltage for Vin ±1V Load : 0.01% of max voltage for full load change Stability 0.02%/Hr Setting voltage accuracy ±0.5%(at maximum output Vcon-in) Temperature coefficient 0.007%/°C Protection Reversible input connection Overload, arc and continuous output short circuit Temperature range Operating : -10°C to +50°C Storage : -25°C to +85°C Weight 30g approx (BOTTOM VIEW) Note : • Specifications are at the maximum rated output after ½Hr warm-up. • Specifications are subject to change without notice. CHARACTERISTICS OF OUTPUT VOLTAGE SETTING 1. PIN , and case are internally connected. 2. CASE PIN should be always connected to ground. 3. Input impedance of Pin is greater than 80k 4. External potentiometer of T.C 100ppm/°C, PC ¼W is recommended.
